Private Objects are an extension mechanism for storing data
in the form of Objects.
They are useful, for example, in the cache interface, where cached
items must be Objects.
The user is responsible for maintaining the data.
In particular, the code creating a Private Object should also specify
a deletion routine that will be called by the executive when the
Object is deleted (to free, for example, any allocated
private memory).
